A new study says testosterone levels drop when guys have kids. Before your guy freaks out because he thinks this means his manhood suffers because of fatherhood, I've got a spoiler alert:
Lower male testosterone levels in this study reflect an improved capacity to care for their children–and that in my opinion also means an improved ability to care for their mates which makes guys even sexier.
Fatherhood may lower the testosterone levels responsible for competing for a mate, but at the same time this hormonal change enhances the ability to be calm and attentive.
